ELECTRIFICATION FEATURE
Motor redesign for zero heavy rare earths should employ a " smart engineering " approach rather than
" brute force adaptation. "
question of the cost of the cooling system. So, there are
other ways to look at this that helps us to be more creative
and not adapt with a brute-force mentality. "
Engineers also must address the need for shorter
charge times and the impact that has on motors. " For
instance, 1200-volt [batteries] is something that's
been looked at; I've heard some of our heavy-duty
" We know of different
higher-sustainability
solutions today, but
they have system-cost
penalties. They even have
sustainability penalties in
some cases, by making
the motor more sustainable
at the expense of the battery
being larger. "
- David Fulton, BorgWarner
customers talking about it as a way to get to faster charge times, "
Fulton said. " But this is going to drive the need for thicker insulation
materials in our motors. Because of creepage and clearance, it
has a power-density penalty. When you have more insulation, you
have less room for copper - as a result, your losses go up in the
motor. For the same range, that's going to have a slight battery-size
penalty associated with it. "
